Abstract
A data processing method, an apparatus, a device and a medium are provided. The method includes: receiving a first set obtained by a second participant shuffling and ID-randomizing its set and replacing features with first-homomorphic-ciphertexts; obtaining a second set by shuffling and ID-randomizing a collection set of the a first participant's set and imitation elements, and replacing features of collection set elements with second-homomorphic-ciphertexts and sending the second set to the second-participant; receiving a third set obtained by the second-participant splitting second homomorphic ciphertexts into second-shared-ciphertexts and second-shared-numbers and replacing the second-homomorphic-ciphertexts with the second-shared-ciphertexts; splitting the first-homomorphic-ciphertexts of intersection elements and confusion elements of third and fourth sets into first-shared-ciphertexts and first-shared-numbers; splitting a first/second preset value to obtain IDs of the intersection/confusion elements; constructing a first-feature-union-set according to the second-shared-ciphertexts, the first-shared-numbers and the IDs; and sending the first-shared-ciphertexts and the IDs to the second participant.
